Description

Anti-bacterial and deodor beads using silver salt of hydroxy acids and it's manufacturing methods

The present invention relates to an antibacterial deodorizing bead using polyacrylate and hydroxyacid including silver nano and a method for producing the same.

More specifically

(a). Hydroxyacid silver nano salts are prepared by using hydroxyacid having excellent deodorizing ability and silver nano having excellent antibacterial activity and stability against substances containing ammonia, amines, and sulfur, which are odor causing substances, and having humidity control ability. It is manufactured in the form of beads using high-absorbency polyacrylate, so it can be used in household goods with antibacterial and deodorizing effect through natural ventilation system by installing in the living space freely without using spraying method such as spray.

(b). The present invention relates to an antibacterial deodorizing bead using hydroxy silver nano salts and polyacrylates that can be reused by adding a hydroxy silver nano salt solution to beads having a reduced volume after use, and a method of manufacturing the same.

Conventional antimicrobial deodorant beads (beads) are manufactured using a flavonoid deodorant which is a plant extract component, but in the case of the deodorant using such flavonoids, the deodorizing power of amines or sulfur compounds having two or more carbon chains has a problem of deterioration. have.

It also contains silver nano for antimicrobial activity, but it is dispersed in surfactant rather than complex or combination with flavonoids. Therefore, it is difficult to obtain uniform antimicrobial effect because silver nano material is leached or precipitated on the vessel wall. Silver nano is easily oxidized and the color becomes dark or yellow, gray or black and has the disadvantage of changing the shape of the product.

In the case of classical beads, the solid phase is typically produced in the form of beads or rods using porous of charcoal and zeolite to remove odor. However, after the gas odor is trapped in the porous charcoal or zeolite, the effect has no effect. As it is offset, it is difficult to expect a lasting effect, and has a disadvantage that its volume is not easy to store.

In addition, if the deodorant in recent years been sold in the product of the tinge to the beads form a raw material of deodorant surfactant and a photocatalyst, even in a small amount was added form the oxygen catalyst, such as, but already reported reportedly photocatalyst is titanium oxide (TiO _2), such as In the case of deodorant additives, the effect of catalysis by ultraviolet irradiation cannot be predicted without ultraviolet irradiation, and it is difficult to expect the effect of the deodorizing additive in the form of dispersion in the appearance of beads.

Beads using other forms of liquid deodorant include those obtained by diluting the raw material liquid and the oil-soluble or solid phase by dissolving or dispersing them with a surfactant. Typical examples are flavonols and sodium carbonate extracted from natural green tea. (NaHCO ₃ ), EDTA, biological preparations using microorganisms, aldehydes, ketones, cyclodextrins, cyclodextrin derivatives, etc., but they are sold in the form of deodorant because of their low compatibility with antibacterial agents.

As described above, when silver nano is added for antibacterial and bactericidal power, silver nano particles having a reducing power are reduced by reducing the raw material used as a deodorant, and the silver nano itself is oxidized to lose antimicrobial and bactericidal effect and has a deodorizing effect. Can be reduced and have the side effect of losing the deodorizing effect.

In the case of a deodorant, a representative liquid deodorant on the market is Pebriz (P & G), but it uses a mechanism of capturing a substance as an odor source using cyclodextrin.

However, due to the limited molecular size of the cyclodextrin trapping is known to exhibit a very limited deodorizing effect, except for some amines, the price is very expensive, the majority is diluted in water with a liquefied formulation It is sold.

Particularly, in the case of liquefied deodorant for textiles, the acidity has an acidity of pH 3.6 ~ 5, so when dried with iron or dryer, it can impair the basic physical properties of the fiber and cause damage to the fiber tissue. There was a problem of limitation, and the deodorization power verification test of the Consumer Protection Agency proved to be low as expected.

In addition, since the cyclodextrin is very susceptible to heat and reacts or decomposes at a high temperature of 100 ° C. or higher, so that the cyclodextrin hardly functions as a deodorant, it is difficult to be used as an industrial deodorant in the manufacturing process of industrial products.

Titanium oxide (TiO ₂ ) is a liquid deodorant that has stability even at high temperatures, but when added to a product, there is a disadvantage that a uniform deodorization effect cannot be obtained because it is not easy to change physical properties and dispersion.

In the case of the deodorants presented in the above example, there is no antibacterial activity, so the deterioration and physical properties of the product can not be avoided when stored at a temperature for a long time or above room temperature.

In order to solve the problems of the prior art, the present invention is prepared in the form of hydroxyacid silver nano-salt to have excellent antibacterial activity without changing the antimicrobial properties of silver nano to hydroxy acid having thermal stability and excellent deodorizing power and excellent stability It is suitable for deodorizing materials containing ammonia, amines, and sulfur, which are odor causing substances, by manufacturing antibacterial deodorant with excellent antibacterial deodorizing power and using absorbent polyacrylate in the form of antibacterial deodorant beads. It can be used as a general purpose deodorant.

In addition, it is an object of the present invention to provide a method for producing antibacterial deodorizing beads that are convenient to use in real life by leaving the room without using a method such as spraying by manufacturing in the form of beads.

In addition, by making renewable eco-friendly antibacterial deodorizing beads to create a more comfortable living environment.

The present invention provides antibacterial deodorizing beads using hydroxyacid silver nano salts.

The present invention provides a first step of separating hydroxyacid from at least one plant selected from the group consisting of castor oil, soybean oil, coconut oil and palm oil, and purifying the separated hydroxyacid, and purification in the first step. The prepared hydroxyacid into a solvent containing nanosilver, followed by stirring, and then removing the solvent to prepare a silver nanosalt of hydroxyacid, and using the hydroxyacid silver nanosalt obtained in the second process. It provides a method for producing antibacterial deodorizing beads using hydroxyacid silver nano salt, including the third process of preparing acrylate beads.

The present invention provides a new use as a hydroxyacid silver nino salt deodorant and a method for preparing the deodorant using natural materials such as castor oil, the deodorization phenomenon according to the silver nano-salt of hydroxy acid is an amine that is a source of odor And chemical bonding with sulfur compounds.

The silver nano salt of the hydroxyacid is generally a fatty acid having 16 or more carbon atoms, which is excellent in thermal stability and does not react or decompose even at about 180 ° C. or more.

Beta-cyclodextrin, a liquid deodorant which has been mainly used as a liquid deodorant in the past, has a cylindrical bonding structure, and has a small molecular size because it has only seven carbon atoms having a reactor that can participate in the capture, Since the metal salt of hydroxyacid has a structure in which two carbon chains having 16 or more carbon atoms face each other, the size of a molecule that can be trapped and bound therein is large.

In addition, by adding nano-sized silver nanoparticles to increase the antimicrobial ability, it is possible to give excellent antimicrobial ability by a mechanism that destroys cell walls and cell membranes of bacteria and fungi.

The silver nanoparticles form a salt with hydroxyacid to form a complex in the form of hydroxyacid silver nanosalts, thereby forming a silver nano compound in a stable form and inhibiting silver nanoparticles from being oxidized in the air to change color. It can express color, maintain the inherent antibacterial and bactericidal power of silver nano, and can obtain uniform dispersion effect without precipitation when dispersing in solution.

In addition, polyacrylate is a super absorbent, usually white powder, which absorbs water in water and swells instantaneously to form a gel. Sodium acrylate can absorb about 1000 grams of water per gram. .

Carboxymethyl cellulose or polyvinyl acrylate is less absorbent than sodium acrylate because it can absorb about 400 grams of water per gram. Since the super absorbent polymer (SAP) has a carboxylic acid group and also has the ability to adsorb ammonia, it can double the performance of deodorization by making beads.

Hydroxyacids of the present invention deodorized beads using silver nano salts and polyacrylates are salts formed by reacting silver nanoparticles with 16 or more carbon atoms of hydroxy acid. Excellent deodorizing effect can be obtained by leaving it in the odor generating space such as amines, amines, sulfur and ammonia. As the silver nano compound forms a hydroxy acid and a salt in a complex form, it can maintain the antimicrobial property inherent in silver nano. By suppressing side effects such as discoloration by the antibacterial deodorizing beads that can express a variety of colors can be obtained.

In addition, the silver nano salt of hydroxyacid is a complex structure of silver nano with excellent antibacterial activity in a structure in which two carbon chains having 16 or more carbon atoms face each other, and have a large molecule size capable of capturing and binding odor generating substances. Even in the case of a large odor component, there is an advantage that can exhibit excellent deodorizing effect and antimicrobial effect, and can be recycled and reused by adding hydroxyacid silver nano solution after use, which can produce eco-friendly antibacterial deodorizing beads.

Hereinafter, the beads including the hydroxyacid, silver nano, and polyacrylate for the antimicrobial deodorant of the present invention will be described in more detail.
